Description
FIELD OF THE INVENTION
[0001] The present invention relates to an image displaying
apparatus and an image display program and more particularly to an
image displaying apparatus and an image display program arranged
for driving the sub pixels independently in its LCD (liquid crystal
display) to improve the resolution along the major axis of the LCD
and displaying a reduced image while maintaining the aspect ratio
of an original image.
BACKGROUND OF THE INVENTION
[0002] An image reducing method is known for reducing a great
number of pixels in an image through simple sampling or operation
sampling to produce an image of a small number of pixels (See
Patent Citation 1).
[0003] Meanwhile, a displaying apparatus is known which drives the
three sub pixels of each pixel independently in its LCD (See Patent
Citation 2).
Patent Citation 1: JP (Heisei)10-327402A
Patent Citation 2: JP 2003-228337A
[0004] There is a demand, for example, for displaying a medical
image recorded with an FPD (flat panel detector) of 4096.times.3328
pixel type on an LCD of 1600.times.1200 pixel type.
[0005] Using the image reduction method of Patent Citation 1, a
medical image of 4096.times.3328 pixels produced by the FPD is
reduced to an image of 1477.times.1200 which can thus be displayed
on the LCD of 1600.times.1200 pixel type. The number of pixels
along the minor axis in the reduced image is set to 1200 because it
corresponds to the number of pixels along the minor axis on the
LCD. The number of pixels along the major axis in the reduced image
is set to 1477 because the aspect ratio of the original image has
to be maintained.
[0006] Since the original image along either of the major axis and
the minor axis is reduced from 2.774 (=4096/1477/1200) pixels to
one pixel for the LCD, its resolution will significantly be
declined.
[0007] More specifically, it is essential for the diagnosis of
breast cancer to identify a tiny pathological sign such as
calcopherite of not greater than 100 .mu.m. As the pitch of its
pixels is generally 70 .mu.m, the FPD has a desired degree of the
resolution. However, since the pitch of pixels on LCD is equivalent
to 194 (=70*2.774) .mu.m of the pitch of pixels on the FPD, a
desired degree of the resolution will hardly be maintained.
[0008] Each pixel on the LCD of the monochrome liquid crystal
display consists of three sub pixels aligned along the major axis
of the LCD. The resolution along the major axis on the LCD can thus
be improved by driving independently the three sub pixels such as
in the display of Patent Citation 2.
[0009] However, while the sub pixels are commonly rectangular in
the shape, the image reducing method of Patent Citation 1 of which
the shape of the pixels is square or circular fails to maintain the
aspect ratio of the original image at the display.
SUMMARY OF THE INVENTION
[0010] It is hence an object of the present invention to provide an
image displaying apparatus and an image display program arranged
for driving the sub pixels independently in the LCD to improve the
resolution along the major axis of the LCD and displaying a reduced
image while maintaining the aspect ratio of an original image.
[0011] As a first aspect of the present invention, an image
displaying apparatus is provided comprising: an image converting
means for reducing and converting an original monochrome image
which comprises an array, m rows and n columns, of pixels into a
display image which comprises an array, q rows and (3*n*q/m)
columns, of pixels where m, n, q, and P are natural numbers and
m.ltoreq.n, q<P, n/m<P/q, and m>q are given; and a
monochrome liquid crystal display provided with a monochrome LCD,
which comprises an array, q rows and P columns, of pixels for
driving the sub pixels independently aligned along the rows of the
monochrome LCD to display the display image on the LCD.
[0012] The image displaying apparatus of the first aspect reduces
and converts the original monochrome image which comprises an
array, m rows and n columns, of pixels into a display image which
comprises an array, q rows and (3*n*q/m) columns, of pixels. As the
number of pixels along the row of the original monochrome image is
(n*q/m) at the aspect ratio (n/m), the number of pixels along the
row in the display image is three times greater than that of the
original monochrome image at the aspect ratio (n/m) of the original
monochrome image. With the three sub pixels of each pixel on the
monochrome LCD aligned along the row and driven independently to
display the display image, the number of pixels along the row on
the monochrome LCD is expressed by (3*n*q/m)/3=(n*q/m).
Accordingly, the aspect ratio of the display image is
(n*q/m)/q=(n/m). In other words, the aspect ratio of the original
image can be maintained.
[0013] The resolution along the row is hence three times higher
than that when the sub pixels are driven not independently. The
pitch of the sub pixels on the LCD is equal at the conversion to
n/(3*n*q/m)=m/(3*q) times greater than the pitch of the pixels on
the FPD in view of the conversion into the pitch of pixels on the
FPD. When the pitch of the pixels on the FPD is 70 .mu.m with
m=3328 and q=1200, for example, the pitch of the sub pixels on the
LCD is equal to 65(=70*3328/(3*1200)) .mu.m for the pitch of the
pixels on the FPD in view of the conversion. Accordingly, the
resolution of 100 .mu.m needed for examining breast cancers can be
achieved.
[0014] As a second aspect of the present invention, an image
display program for displaying an original monochrome image which
comprises an array, m rows and n columns, of pixels on a monochrome
LCD, which comprises an array, q rows and P columns, of pixels, of
a monochrome liquid crystal display where m, n, q, and P are
natural numbers and m.ltoreq.n, q<P, n/m<P/q, and m>q are
given, is provided allowing a computer to act as an original
monochrome image inputting means for inputting the original
monochrome image from the outside, an image converting means for
reducing and converting the original monochrome image into a
display image which consists of an array, q rows and (3*n*q/m)
columns, of pixels, and a display image outputting means for
outputting the display image to the monochrome liquid crystal
display in order to display the display image through independently
driving the sub pixels of the monochrome LCD.
[0015] The image display program of the second aspect reduces and
converts the original monochrome image which consists of comprises
an array, m rows and n columns, of pixels into a display image
which comprises an array, q rows and (3*n*q/m) columns, of pixels.
As the number of pixels of the original monochrome image is (n*q/m)
at the aspect ratio (n/m), the number of pixels along the row in
the display image is three times greater than that of the original
monochrome image. With the three sub pixels of each pixel on the
monochrome LCD aligned along the row and driven independently to
display the display image, the number of pixels along the row on
the monochrome LCD is expressed by (3*n*q/m)/3=(n*q/m).
Accordingly, the aspect ratio of the display image is
(n*q/m)/q=(n/m). In other words, the aspect ratio of the original
image can be maintained.
[0016] The resolution along the row is hence three times higher
than that when the sub pixels are driven not independently. The
pitch of the sub pixels on the LCD is equal to n/(3*n*q/m)=m/(3*q)
times greater than the pitch of the pixels on the FPD in view of
the conversion into the pitch of pixels on the FPD. When the pitch
of the pixels on the FPD is 70 .mu.m with m=3328 and q=1200, for
example, the pitch of the sub pixels on the LCD is equal to
65(=70*3328/(3*1200)) .mu.m for the pitch of the pixels on the FPD
in view of the conversion. Accordingly, the resolution of 100 .mu.m
needed for examining breast cancers can be achieved.
ADVANTAGES OF THE INVENTION
[0017] The image displaying apparatus and the image display program
according to the present invention allow the image to be reduced
from an original image with the aspect ratio remaining unchanged
and displayed on the LCD while the resolution along the major axis
is improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0033] FIG. 1 is a schematic view of a medical image displaying
apparatus 1 illustrating Embodiment 1.
[0034] The medical image displaying apparatus 1 comprises a
personal computer 3 for carrying out a medical image viewer program
31 where, when m.ltoreq.n, q<P, n/m<P/q, and m>q where m,
n, q, and P are natural numbers, a monochrome medical image data
A(i, j) which consists of an array, m rows and n columns, of pixels
is entered and converted into a display image data M(k, L) which
consists of a reduced array, q rows and (3*n*q/m) columns, of
pixels and a monochrome liquid crystal display 4 equipped with a
monochrome LCD panel which is composed mainly of an array, q rows
and P columns, of pixels for displaying the display image data M(k,
L) through independently driving the sub pixels aligned along the
rows of the monochrome LCD panel.
[0035] The monochrome medical image data A(i, j) has been recorded
with an FPD in a medical imaging apparatus F which consists of an
array, m rows and n columns, of pixels and saved in a medical image
data server D.
[0036] When m<n, the major axis of the medical image data A(i,
j) is commonly determined to extend along the up-and-down direction
of a subject to be examined thus allowing the major axis of the LCD
to extend along the up-and-down direction. It is however assumed
for ease of the description that both the medical image data A(i,
j) and the LCD are extended longer along the horizontal
direction.
[0037] FIG. 2(a) illustrates a numerical example of the monochrome
medical image data A(i, j) where m=3328 and n=4096.
[0038] FIG. 2(b) illustrates a numerical example of the LCD where
q=1200 and P=1600.
[0039] FIG. 3 is an explanatory view showing the relationship
between the LCD and the display image data M(k, L).
[0040] As n/m<P/q is given, the monochrome medical image data
A(i, j) is reduced so that the minor axis of the LCD extends along
the minor axis of the display image data M(k, L). When the aspect
ratio n/m of the monochrome medical image data A(i, j) is
maintained, the number p of pixels along the major axis of the
display image data M(k, L) becomes smaller than the number P of
pixels along the major axis of the LCD.
[0041] For example, with m=3328, n=4096, q=1200, and P=1600,
p=4096*1200/3328=1477 is established.
[0042] As shown in FIG. 4, each pixel U in the LCD consists of
three sub pixels u1, u2, and u3 aligned along the major axis of the
LCD. Since the pixel U is arranged of a square shape, the shape of
the sub pixels u1, u2, and u3 is rectangular.
[0043] FIGS. 5 and 6 are flowcharts showing procedures of a medical
image viewer process of the medical image view program 31 in the
personal computer 3.
[0044] At Step S0, the monochrome medical image data A(i, j)
comprising an array, m rows and n columns, of pixels is read out
from the medical image data server 2.
[0045] At Step S1, a reduction rate ry=m/q along the minor axis is
calculated from the number m of pixels along the minor axis of the
monochrome medical image data A(i, j) and the number q of pixels
along the minor axis on the LCD. For example, ry=2.774 is given
with m=3328 and q=1200.
[0046] At Step S2, a minor axially weighted average weight
b=(ry-1)*B is calculated from the reduction rate ry along the minor
axis and an adjusting factor B. For example, b=0.2129 is given when
ry=2.774 and B=0.12. This allows an operator to control the
appearance (with image noises) of the display image through
adjusting the adjusting factor B.
[0047] At Step S3, a weighted average image data A'(i, j) which is
a result of weighted averaging the medical image data A(i, j) along
the minor axis is calculated from the medical image data A(i, j)
and the minor axially weighted average weight b so that all the
pixels of the medical image data A(i, j) appear in the display
image.
[0048] FIG. 7 illustrates structural concepts of the medical image
data A(i, j) and the minor axially weighted average image data
A'(i, j).
[0049] As apparent from FIG. 8 and the following equation, the
minor axially weighted average image data A'(i, j) is calculated by
weighted averaging the three adjacent medical image data A(i, j-1),
A(i, j), and A(i, j+1), because the minimum integer which is
greater than the reduction rate ry=2.774 along the minor axis is
3.
A'(i, j)=A(i, j-1)*b+A(i, j)*(1-2*b)+A(i, j+1)*b
where A'(i, 0)=A(i, 0) and A'(i, m-1)=A(i, m-1).
[0050] i=0, 1, . . . , n-1, j=0, 1, . . . , m-1.
[0051] In common, when the integer which is greater than the
reduction rate ry along the minor axis is (2*g+1), the minor
axially weighted average image data A'(i, j) is calculated by
weighted averaging the adjacent medical image data A(i,j-g), . . .
, A(i, j+g). The minor axially weighted average weight may be
determined depending on g.
[0052] At Step S4, the image column coordinate i is initialized to
zero.
[0053] At Step S5, the LCD minor axial coordinate L is initialized
to zero.
[0054] At Step S6, an image reference coordinates jq=int(L*ry)
along the minor axis is calculated with the LCD minor axial
coordinate L.
[0055] At Step S7, a minor axial interpolation weight
Wy(L)=(L*ry)-jq is calculated.
[0056] At Step S8, a minor axially interpolated intermediate image
data C(i, L) is calculated by linearly interpolating the minor
axially weighted average image data A'(i, j) and the minor axial
interpolation weight Wy(L) as shown in FIG. 9 and the following
equation.
C(i, L)=A'(i, jq)*(1-Wy(L))+A'(i, jq+1)*Wy(L)
[0057] At Steps S9 and S10, the action at the steps S6 to S8 is
repeated until L reaches (q-1).
[0058] At Steps S11 and S12, the action at the steps S5 to S10 is
repeated until i reaches (n-1).
[0059] As described and shown in FIG. 10, the minor axially
weighted average image data A'(i, j) is converted into the minor
axially interpolated intermediate image data C(i, L).
[0060] Referring to FIG. 6, at Step S13, the number p=n/ry of
pixels along the major axis of the LCD used for actually displaying
along the major axis on the LCD is calculated. For example, p=1477
is established when n=4096 and ry=2.774.
[0061] At Step S14, a reduction rate rx=n/(p*3) along the major
axis is calculated from the number (p*3) of sub pixels which is a
result of multiplying the number p of pixels by three for
independently driving the three sub pixels along the major axis in
each pixel of the LCD. For example, rx=0.9244 is established when
n=4096 and p=1477.
[0062] At Step S15, the LCD major axial coordinate k is initialized
to zero.
[0063] At Step S16, a major axial image reference coordinate
ip=int(k*rx) corresponding to the major axial LCD coordinate k is
calculated.
[0064] At Step S17, a major axial interpolation weight
Wx(k)=(k*rx)-ip is calculated.
[0065] At Step S18, the LCD minor axial coordinate L is initialized
to zero.
[0066] At Step S19, a display image data M'(k, L) is calculated by
linearly interpolating the minor axially interpolated intermediate
image data C(i, L) with the major axial interpolation weight Wx(k)
as shown in FIG. 11 and the following equation.
M'(k, L)=C(ip, L)*(1-Wx(k))+C(ip+1, L)*Wx(k)
[0067] At Steps S20 and S21, the action at Step S19 is repeated
until L reaches (q-1) before the procedure advances to Step
S22.
[0068] At Steps S22 and S23, the action at the steps S16 to S21 is
repeated until k reaches (p*3-1) before the procedure advances to
Step S24. Accordingly, as shown in FIG. 12, the display image data
M'(k, L) is obtained.
[0069] At Step S24, the display image data M'(k, L) is subjected to
the frequency enhancing process by weighted calculation at three
points for improving the resolution along the minor axis, thus
calculating the final display image data M(k, L). Accordingly, the
final display image data M(k, L) is obtained as shown in FIG.
13.
M(k, L)=M'(k, L-1)*e+M'(k, L)*(1-2*e)+M'(k, L+1)*e
where M(k, 0)=M'(k, 0), M(k, q-1)=M'(k, q-1), k=0, 1, . . . , p*3-1
and L=0, 1, . . . , q-1. Also, e is a weighted factor for use in
the frequency enhancing process as ranging, for example, from -0.1
to -0.2 in view of the balance with the direction of the major axis
and the impression of a displayed image.
[0070] At Step S25, the display image data M(k, L) is transferred
from the personal computer 3 to the monochrome liquid crystal
display 4.
[0071] The monochrome liquid crystal display 4 drives the sub
pixels of the LCD independently to display the display image data
M(k, L) as shown in FIG. 14.
[0072] The advantages of the medical image displaying apparatus 1
with the medical image viewer program 31 of Embodiment 1 are as
follows.
[0073] (1) The number of the sub pixels along the major axis of the
LCD to be actually used for display is (p*3) which is equivalent to
the number (n*q/m) of the pixels in view of the conversion into the
number of pixels. Accordingly, the aspect ratio of the display
image is expressed by (n*q/m)/q=(n/m). More particularly, the
aspect ratio of the medical image data A(i, j) can be
maintained.
[0074] (2) The resolution along the major axis is three times
greater than that when the sub pixels are driven not independently.
The pitch of the sub pixels on the LCD is equal at the conversion
to n/(3*n*q/m)=m/(3*q) times greater than the pitch of the pixels
on the FPD in view of the conversion into the pitch of pixels on
the FPD. For example, when the pitch of the pixels on the FPD is 70
.mu.m with m=3328 and q=1200, the pitch of the sub pixels on the
LCD is equal to 65 (=70*3328/(3*1200)) .mu.m for the pitch of the
pixels on the FPD in view of the conversion. Accordingly, the
resolution of 100 .mu.m needed for examining breast cancers can be
achieved.
[0075] The image displaying apparatus and the image display program
according to the present invention can favorably be used for
increasing the efficiency of the action of doctors examining
various medical photos including X-ray images, CT images, and MR
images for diagnostic purposes.
